Brief Summary
This study will evaluate the use of two different bifocal contact lens add powers to prevent further nearsighted progression in children ages 7 to 11 years old. It is theorized that the profile of the bifocal lenses will decrease the amount of change in nearsightedness that the children experience.

Outcome Measures
Primary Outcomes (1)
Refractive Error Progression
Refractive error, as measured by cycloplegic autorefraction in both eyes, will be measured yearly to assess the difference in progression between the two soft bifocal treatment lenses (+1.50 D add and +2.50 D add) and the control group (soft spherical contact lenses).

Biofinity
ACTIVE COMPARATORSoft spherical contact lens
Biofinity Multifocal D +1.50 add
EXPERIMENTALThe Biofinity Multifocal "D" with a +1.50 add is a soft bifocal contact lens that has a medium reading power
Biofinity Multifocal D +2.50 add
EXPERIMENTALThe Biofinity Multifocal "D" with a +2.50 add is a soft bifocal contact lens that has a strong reading power
Interventions

Eligibility Criteria
You may qualify if:
- to 11 years, inclusive, at baseline examination
- to -5.00 D, inclusive, spherical component, cycloplegic autorefraction
- ≤1.00 DC, cycloplegic autorefraction
- ≥ 2.00 D difference between the sphere components of the two eyes (anisometropia), cycloplegic autorefraction
- logMAR or better best-corrected visual acuity in each eye
- logMAR or better visual acuity OU distance and near with a +2.50 D add contact lens
- +2.50 D add lens provides adequate fit with respect to movement and centration
You may not qualify if:
- Eye disease or binocular vision problems (e.g., strabismus, amblyopia, oculomotor nerve palsies, corneal disease, etc.)
- Systemic disease that may affect vision, vision development, or contact lens wear (eg, diabetes, Down syndrome, etc.)
- Previous gas permeable, soft bifocal, or orthokeratology contact lens wear or bifocal/PAL spectacle wear (longer than 1 month of wear)
- Previous or current participation in myopia control studies
- Chronic use of medications that may affect immunity, such as oral or ophthalmic corticosteroids for ocular or systemic diseases
- Issues that may interfere with the ability to participate over the next 3 years
